Orashi River (also Urashi or Ulasi),[1] is a major river of the lower Niger River basin, and a tributary of Oguta Lake, southeastern Nigeria.[1][2] [3] [4] Orashi takes off, 183 m above mean sea level, from the hills of Dikenafai, (latitude 05 045’N, longitude 07 010’E) in Imo State.[1][5]
Flow
From Dikenafai, Orashi flows through several towns, including Urualla, Akokwa, Okija, Osu, Ukpor, Ihiala, Uli, Oguta, Mgbidi, Omoku, Obiakpo, Ebocha, Ukodu and Mbiama.[1][5] The river forms tributaries along its flow, from Imo through Anambra, before empting onto the Altlantic via Bonima River in Rivers State.[5][1]
Economy
Orashi region is in the rainforest zone, southeastern Nigeria.[1] Crop cultivation, Oil Palm and fishing are the major occupation of the people and source of livelihood.[4]: 3 The zone may be termed an ‘oil palm bush.’[1] The forest zone is characterized by abundance of plant species, sometimes exceeding 150 different species per hectare. From its source down to the Atlantic, the river supports several fishermen and provides means of liveli-hood for their families.[1] Orashi Region, which includes Njaba River basin, has over 35% of the oil wells in the Niger Delta states of Imo and Rivers.[4]: 3 [6]
Inland Waterway
Orashi river as an ancient trade and cultural route, has provided means of transportation for indigenous communities who moved from one town to another by canoe, for economic purposes or to convey farm produce on market days.[1] To improve inland waterways in Nigeria, the Federal Government approved the [7] the dredging of the Orashi River from Oguta Lake in Imo State to Degema in Rivers State.[8] The project which was awarded to Simidia S and I International Company in May 2012 was to be completed in 12 months. The 205 kilometers river was expected to be dredged with a bed width of 40 meters, top width of 70 meters and depth below dredging chart datum of 1.5 meters.[9]
